Add a HAPI FHIR adapter

[cmungall]

We have a PR for exporting FHIR JSON:

• Converter: OWL to FHIR CodeSystem #320.

This could be used for loading a HAPI FHIR server using any OAK-wrapped ontology

It would be useful to have the converse operation - the ability to talk to a HAPI FHIR server

Example code: https://github.com/HOT-Ecosystem/TSDemoBoard/blob/master/CodeSystem.ipynb

@joeflack4 - are there existing python clients we can wrap?

I think this kinda FHIR client / stuff would be a good to add to OAK in some way or another. For the TSDemoBoard, the client there is mainly to simplify the Jupyter notebook. The only Python client I remember specifically looking at is the smart-on-fhir one that you linked. I haven't spent much time looking at it, though.

Yes, this seems pretty straightforward to use:

Doesn't seem to introduce a lot of dependencies which is nice, we could incorporate directly rather than as a plugin
